Microwave-Accelerated Click Chemistry: Expeditious Synthesis of Novel Triazole-linked Salicylic β-D-O-Glycosides with PTP1B Inhibitory Activity

다국어 초록 (Multilingual Abstract)

The incorporation of microwave irradiation with the prevalent “click chemistry” is currently of considerable synthetic interest. We describe here the introduction of such laboratorial shortcut into carbohydrate-based drug discovery,resulting in the rapid formation of a series of triazole-linked salicylic β-D-O-glycosides with biological activities. All “clicked” products were achieved in excellent yields (≈ 90%) within only a quarter. In addition, based on the structural characteristics of the afforded glycomimetics, their inhibitory activities were evaluated toward protein tyrosine phosphatases 1B (PTP1B) and a panel of homologous protein tyrosine phosphatases (PTPs). Docking simulation was also conducted to plausibly propose binding modes of this glycosyl salicylate series with the enzymatic target.
